  • Stretch marks are a normal, common part of pregnancy, caused by skin stretching, hormones, and genetics. 
  • They often appear on the bump, breasts, hips, thighs, and bottom, starting red or purple and fading over time. 
  • Caring for stretch marks involves regular hydration and sun protection. 
  • Stretch marks are nothing to be ashamed of; they’re a natural sign your body is growing and nurturing your bub. 

Pregnancy brings incredible changes to your body, and with those changes, it’s common to notice new marks on your skin. Most pregnant people will get stretch marks, and they’re completely normal.  

In this guide, we’ll explain what stretch marks look like, why and where they appear, and share some tips on how you can care for your skin throughout pregnancy and beyond. 

What are stretch marks? 

Stretch marks are lines or streaks on the skin caused by rapid stretching. During pregnancy, they often appear on the bump, breasts, hips, thighs, and bottom. At first, they can look red, purple, or pink, and over time, they tend to fade to a silvery-white colour. 

Tips for caring for stretch marks during and after pregnancy

  1. Apply moisturiser daily to keep your skin supple and soothe any itchiness.
  2. Protect marks from the sun to prevent them darkening.
  3. Most stretch marks naturally fade over time after birth.
  4. Postpartum treatments are available but completely optional.

Why stretch marks happen during pregnancy 

  • Skin stretching: As your bump and breasts grow, your skin stretches quickly, which can cause these marks. 
  • Hormonal changes: Pregnancy hormones affect the elasticity of your skin, making it more prone to tearing beneath the surface. 
  • Genetics: If your mum or sisters had stretch marks, you’re more likely to get them too. 

Who’s most at risk? 

  • First pregnancies may show more noticeable stretch marks. 
  • Certain skin types are more prone, particularly if skin is less elastic. 
  • Rapid or significant weight gain can increase the likelihood of stretch marks. 

How to prevent or reduce stretch marks

  1. Moisturising and hydration: Keep your skin nourished with creams, oils, or butters. Look for pregnancy-safe ingredients like Cocoa Butter, Shea Butter, Almond Oil, or Vitamin E.
  2. Healthy weight gain: Gradual, steady weight gain puts less stress on your skin.
  3. Gentle exercise: Regular movement encourages circulation and supports skin health.

Top tip

There’s no guaranteed way to prevent stretch marks entirely; genetics are a key factor.

When to see a GP or midwife 

If stretch marks are very itchy, painful, or change suddenly, speak to your GP or midwife. It’s always better to get a professional opinion if you’re worried. 

Embracing your changing body 

Stretch marks are a common and natural part of pregnancy. They show your body adapting to support your bub, reflect the amazing work it’s doing, and are nothing to be ashamed of. 

By moisturising, maintaining healthy habits, and practising patience, you can care for your skin while embracing the changes. Remember: your body is nurturing life, stretch marks are simply part of that story. 

When do stretch marks usually appear?

They can appear at any point during pregnancy, but most commonly in the second and third trimesters as your bump and breasts grow.

Yes. Most stretch marks fade slightly over time, changing from red or purple to a silvery-white colour, though they may never disappear completely.
